I want to upload the image to the server.
I got the bitmap of the image and encoded it to base64.
I convert the base64 of the image to a string using the encodeToString method.
I post the string to PHP using httpurlconnection. Actually, I got the string from PHP which is not the whole string. I don`t get any error. Please give me feedback!
public String httpURLConnectionPost(final String urlString){
String result="";
try {
URL url = new URL(urlString);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setUseCaches(false);
connection.connect();
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.download);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] imageBytes = baos.toByteArray();
String encodedImage = Base64.encodeToString(imageBytes, Base64.NO_CLOSE);
String body= "image="+encodedImage;
Log.d("serverPostData","body = " +body);
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(connection.getOutputStream(), "UTF-8"));
writer.write(body);
writer.close();
int responseCode = connection.getResponseCode();
if(responseCode == HttpURLConnection.HTTP_OK){
InputStream inputStream = connection.getInputStream();
StringBuilder stringBuilder = new StringBuilder();
String line;
BufferedReader br = new BufferedReader(new InputStreamReader(inputStream));
while ((line = br.readLine()) != null) {
stringBuilder .append(line);
}
result = stringBuilder .toString();
}
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
The php got the string and decode it.
<?php
include("mysqli_connect.php");
$image= $_POST['image'];
$a = uniqid() ;
$ImagePath = "good/$a.JPEG";
$ServerURL = "https://172.30.10.1/$ImagePath";
$InsertSQL = "INSERT INTO Photoshop(photo) VALUES('$ServerURL')" ;
if(mysqli_query($connect, $InsertSQL)){
file_put_contents($ImagePath,base64_decode($image));
echo $image;
}else{
echo "failed";
}
mysqli_close();
?>
Try this to convert image to base64:
Uri uri = data.getData();
Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uri);
String encodedImageData = getEncoded64ImageStringFromBitmap(bitmap);
Now pass the data in API:
JsonObject data1 = new JsonObject();
data1.addProperty("imageData", "data:image/png;base64," + encodedImageData);
Now set ImageBitmap:
image.setImageBitmap(bitmap);
Here is the method:
private String getEncoded64ImageStringFromBitmap(Bitmap bitmap) {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 70, stream);
byte[] byteFormat = stream.toByteArray();
// get the base 64 string
String imgString = Base64.encodeToString(byteFormat, Base64.NO_WRAP);
return imgString;
}
And for HttpUrlConnection try this...
jsonObject = new JSONObject();
jsonObject.put("imageString", encodedImage);
String data = jsonObject.toString();
String yourURL = "yourphpfileurl";
URL url = new URL(yourURL);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestMethod("POST");
connection.setFixedLengthStreamingMode(data.getBytes().length);
connection.setRequestProperty("Content-Type", "application/json;charset=UTF-8");
OutputStream out = new BufferedOutputStream(connection.getOutputStream());
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(out, "UTF-8"));
writer.write(data);
writer.flush();
writer.close();
out.close();
connection.connect();
InputStream in = new BufferedInputStream(connection.getInputStream());
BufferedReader reader = new BufferedReader(new InputStreamReader(
in, "UTF-8"));
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line);
}
in.close();
String result = sb.toString();
connection.disconnect();
Hope this one will work for you...
I solved my probelm that the base64 need to replace empty to "+".
<?php
include("mysqli_connect.php");
$image= $_POST['image'];
$change = str_replace(" ","+",$image);
$a = uniqid() ;
$ImagePath = "good/$a.JPEG";
$ServerURL = "https://172.30.10.1/$ImagePath";
$InsertSQL = "INSERT INTO Photoshop(photo) VALUES('$ServerURL')" ;
if(mysqli_query($connect, $InsertSQL)){
file_put_contents($ImagePath,base64_decode($change ));
echo $image;
}else{
echo "failed";
}
mysqli_close();

JSONObject response = null;
String json = "";
HttpURLConnection urlConnection = null;
try {
URL url = new URL(http);
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setDoInput(true);
urlConnection.setDoOutput(true);
urlConnection.setUseCaches(false);
urlConnection.setRequestMethod("POST");

out.writeBytes(line1);
out.flush();
out.close();

String line = null;
while ((line = br.readLine()) != null) {
sb.append(line + "\n");
}
br.close();
json = sb.toString();
response = new JSONObject(json);
} catch (MalformedURLException e) {
} catch (IOException e) {
} catch (JSONException e) {
} finally {
if (urlConnection != null) urlConnection.disconnect();
}
return response;
}
The problem is it is not encoding properly and I am getting output like this -
Example: For a word "How are you" in Hindi i.e "क्या हाल" as 9 & HG 08 * E
Can I get some help please. Thanks in advance.
Try using Html.fromHtml(yourTranslatedStr).toString().
I tried that with Hindi and it worked.

i am working on a system and need to fetch file from the URL using java URLConnection, Now all i need to copy that contents into excel file.
here is my code.
class getsize {
public static void main(String args[]) throws Exception {
HttpURLConnection conn = null;
try {
String plainCreds = "hmhinstall:hmh201208";
// String url = "http://content.link-systems.com/~hbern/content_update/";
byte[] plainCredsBytes = plainCreds.getBytes();
String base64CredsBytes = Base64.encode(plainCredsBytes);
String base64Creds = base64CredsBytes;
System.out.println(base64Creds);
int code = 0;
URL url = new URL("http://content.link-systems.com/~hbern/content_update/ ");
//Reading
URLConnection uc = url.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(
uc.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null) {
System.out.println(inputLine); //Printing file data
}
in.close();
//Getting size
conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
conn.setRequestProperty("Authorization", "Basic " + base64Creds);
conn.setRequestProperty("Content-Type", "application/json;charset=UTF-8");

I want to pass a java application sent a string that is a json,it isn't get this json in servlet, how do I do, who can help me?
This is my servlet code:
public void service(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
BufferedInputStream in = new BufferedInputStream(req.getInputStream());
byte[] data = null;
byte[] bts = new byte[1024];
int index;
while ((index = in.read(bts)) >= 0) {
if (data == null) {
data = new byte[index];
System.arraycopy(bts, 0, data, 0, index);
}
else {
byte[] tmp = data;
data = new byte[tmp.length + index];
System.arraycopy(tmp, 0, data, 0, tmp.length);
System.arraycopy(bts, 0, data, tmp.length, index);
}
}
String json = new String(data);
System.out.print(json);
}
and this is my java application:
String _url = "http://localhost:8080/jsf/test";
URL url = null;
HttpURLConnection urlconn = null;
String json = URLEncoder.encode(JSONObject.fromObject(req)
.toString(), "UTF-8");
url = new URL(_url);
urlconn = (HttpURLConnection) url.openConnection();
urlconn.setRequestMethod("POST");
urlconn.setDoOutput(true);
urlconn.setDoInput(true);
OutputStream out = urlconn.getOutputStream();
out.write(json.getBytes("UTF-8"));
out.flush();
out.close();
BufferedReader rd = new BufferedReader(new InputStreamReader(
urlconn.getInputStream(), "UTF-8"));
StringBuffer sb = new StringBuffer();
int ch;
while ((ch = rd.read()) > -1) {
sb.append((char) ch);
}
System.out.println(sb);
rd.close();
You should write json data to outputStream as out.write(json.getBytes()); . See the complete code below:
String _url = "http://localhost:8080/jsf/test";
URL url = new URL(_url);
String json = "[{\"id\":\"DFAB8108D69642EBBD461160B4519B0F\",\"name\":\"name1\"},{\"id\":\"B048B2521A5619DCE0440003BA11CFDA\",\"name\":\"name2\"}]";
HttpURLConnection urlconn = (HttpURLConnection) url.openConnection();
urlconn.setRequestMethod("POST");
urlconn.setDoOutput(true);
OutputStream out = urlconn.getOutputStream();
out.write(json.getBytes());
out.flush();
out.close();
BufferedReader rd = new BufferedReader(new InputStreamReader(
urlconn.getInputStream(), "UTF-8"));
StringBuffer sb = new StringBuffer();
int ch;
while ((ch = rd.read()) > -1) {
sb.append((char) ch);
}
System.out.println(sb.toString());
rd.close();
Try something like this
String _url = "http://localhost:8080/jsf/test";
URL url = new URL(_url);
String json = "[{\"id\":\"DFAB8108D69642EBBD461160B4519B0F\",\"name\":\"name1\"},{\"id\":\"B048B2521A5619DCE0440003BA11CFDA\",\"name\":\"name2\"}]";
HttpURLConnection urlconn = (HttpURLConnection) url.openConnection();
urlconn .setDoOutput(true);
urlconn .setRequestProperty("Content-Type", "application/json");
urlconn .setRequestProperty("Accept", "application/json");
urlconn .setRequestMethod("POST");
urlconn .connect();
OutputStream os = httpcon.getOutputStream();
os.write((json.getBytes("UTF-8"));
os.close();
